Bit of stuff and nonsense about dressing grilled fowl
I believe the answer is:
spatchcock
'grilled fowl' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for spatchcock that I've seen before include "preparation of The Birds?" , "Game bird split down the back and grilled" , "Chicken or game bird split open and grilled" , "cooked fowl" , "Inappropriately insert" .)
